Embodiment 2
In order by reasonable manner more communication base station to be lowered the temperature, according to described temperature gap, the combination of switching convertible frequency air-conditioner, heat exchanger or convertible frequency air-conditioner and heat exchanger is lowered the temperature to described communication base station, as shown in Figure 3, comprising:
1020, judge temperature gap and the temperature difference threshold value that sets between relation;

1022, when described temperature gap be on the occasion of and during greater than described temperature difference threshold value, then by described heat exchanger described communication base station is lowered the temperature;
1023, when described temperature gap is negative value, then the described heat exchanger of light ratio is lowered the temperature to described communication base station by described convertible frequency air-conditioner.
Compare according to the temperature difference threshold value that sets in the temperature gap that has obtained and the communication base station, wherein said temperature difference threshold value can obtain by long-term experiment, in the process of experiment, at first obtains the caloric value of employed communication base station,
The caloric value of this communication base station=temperature difference * (unit temperature exchange capability of heat+thermal leakage ratio);
For example temperature difference threshold value can be set to 10 degree.
According to two temperature sensors that are arranged at respectively in the communication base station and communication base station is outer, obtain respectively temperature and environment temperature in the station.
Temperature is 51 degree in the station, and environment temperature is 36 when spending, and determines that temperature in the station is 15 to spend with respect to the temperature gap of environment temperature; At this moment, temperature gap is greater than the temperature difference threshold value that sets, the cooling demand that can satisfy communication base station by heat exchanger then is described, the electric energy that consumes when adopting the heat exchanger mode more to save communication base station lowered the temperature is to improve the energy-saving horizontal of communication base station.
As shown in Figure 4, described heat exchanger comprises: be arranged at the evaporimeter in the described communication base station and be arranged at the outer condenser of described communication base station, the setting position of wherein said evaporimeter is lower than the setting position of described condenser, the process of then by heat exchanger communication base station being lowered the temperature, as described below:
The above-mentioned heat exchanger of evaporimeter and condenser that comprises can be gravity heat pipe heat exchanger, and cold-producing medium circulates among heat exchange manifold; At the evaporimeter place of heat exchanger, the refrigerant liquid in the heat exchanger pipeline evaporates, thereby refrigerant liquid is evaporated to refrigerant gas, the heat that is produced to absorb the communication base station internal burden; The direction circulation of refrigerant gas arrow in the heat exchange manifold; When described refrigerant gas arrived condenser, refrigerant gas was met condensation and is become refrigerant liquid, and discharged wherein entrained heat; Refrigerant liquid is got back to the evaporimeter place again, absorbs heat; In the heat exchanger of communication base station, carry out the circulation of cold-producing medium in above-mentioned mode, so that the heats that electrical equipment was produced such as communication base station internal burden are carried out the communication base station outside.
Further, the heat that can the blower fan by being arranged at the condenser place will produce at the condenser place blow out communication base station, and be the communication base station cooling by the cold air that the blower fan that is arranged at the evaporimeter place will form at the evaporimeter place communication base station of coming in and going out.
When described heat exchanger is plate type heat exchanger, by the process that heat exchanger is lowered the temperature to communication base station, as described below:
In communication base station as shown in Figure 1, blower fan is set to realize the circulation of refrigerant gas in heat exchange manifold, inner at communication base station, the refrigerant gas absorbing heat, and in the heat exchange manifold outside communication base station entrained heat is shed, thereby realization is for the cooling of communication base station.
When described heat exchanger was pipe heat exchanger, optional described heat exchanger comprised: pump.By the process that heat exchanger is lowered the temperature to communication base station, as described below:
As shown in Figure 1, when lowering the temperature by pipe heat exchanger, start pump, under the effect of pump, make the refrigerant liquid circulation in the heat exchange manifold, in order to by the refrigerant liquid in the heat exchange manifold heat in the communication base station is taken out of, thereby communication base station is lowered the temperature.
Further, can also blower fan be set in the position of carrying out heat exchange, by the blower fan communication base station that rapidly heat shed, or cold air be blown in the communication base station, improve the cooling efficient of heat exchanger with this.
It generally is the circulation that realizes cold-producing medium in the heat exchange manifold by thermal convection current mode, evaporimeter and condenser or the pump of the less cold-producing medium nature of energy consumption in the process of lowering the temperature by heat exchanger, so the power consumption of communication base station is also less, thereby reduced the electric energy that consumes when communication base station lowered the temperature.
In the process of communication base station being lowered the temperature by pipe heat exchanger, if environment temperature is higher than temperature in the station, for example, temperature is 32 degree in the station, environment temperature is 37 when spending, determine that the interior temperature in station is-5 degree with respect to the temperature output value of environment temperature, temperature gap is negative value, and explanation can't be lowered the temperature to communication base station by heat exchanger, communication base station is lowered the temperature by heat exchanger if continue this moment, then can cause in pipe heat exchanger refrigerant liquid to bring the heat outside the communication base station into communication base station, in order to prevent such problem, as shown in Figure 5, describedly close described heat exchanger, by described convertible frequency air-conditioner described communication base station is lowered the temperature, comprising:
200, close described pump;
203, starting described convertible frequency air-conditioner lowers the temperature to described communication base station.
When environment temperature greater than the station in during temperature, in order to prevent that outside heat from entering communication base station, then close pump set on the heat exchange manifold, thereby stop to flow of refrigerant liquid in the heat exchange manifold, avoided the refrigerant liquid of high temperature to flow into communication base station, made the inner intensification of communication base station.
In addition, when heat exchanger is gravity heat pipe heat exchanger, because the characteristic of its one-way flow, so within environment temperature is higher than the station during temperature, can't finish the circulation of cold-producing medium, just can avoid the heat that communication base station is outer to bring communication base station into, but at this moment, because the refrigerant circulation in the heat exchange manifold stops, also just can't lowering the temperature to communication base station.
Can certainly valve be set at heat exchange manifold, and the control of the folding by by-pass valve control cold-producing medium in heat exchange manifold circulation or stop; When the environment temperature outside detecting communication base station is higher than in the station in the communication base station temperature, valve-off then, thus the cold-producing medium that prevents the high temperature in the heat exchange manifold enters communication base station by circulation.
After heat exchanger cuts out, in order to continue that communication base station is lowered the temperature, then need by convertible frequency air-conditioner communication base station to be lowered the temperature.Convertible frequency air-conditioner can have respectively DC Frequency Conversion Technology or alternating frequency conversion technique according to the situation of reality; Convertible frequency air-conditioner with converter technique, can start with less frequency, corresponding starting current is also less, and the damage of the electrical equipment such as load in the excessive communication base station that is caused of immediate current when avoiding fixed frequency air conditioner to start is to prolong the service life of communication base station; And can under the environment of low temperature, start, also widen the applicable scene of communication base station.
When carrying out work by less startup frequency, frequency-changeable compressor can turn round under the low speed, communication base station inside is lowered the temperature at a slow speed keeps the temperature in the communication base station better, avoided occurring the situation that the interior temperature fluctuation of communication base station is large or can't in time dispel the heat.
When the temperature control that communicates the base station by convertible frequency air-conditioner, by the evaporimeter in the convertible frequency air-conditioner, the refrigerant liquid in the air-conditioning duct is evaporated, be converted into refrigerant gas, in this process, absorb the heat that the communication base station internal burden produces; Start frequency-changeable compressor, by frequency-changeable compressor refrigerant gas is compressed, also improve the temperature of refrigerant gas simultaneously; The refrigerant gas of HTHP moves to condenser and condenses rapidly, emit a large amount of heats, and the heat exchanger fin by stacked setting is promptly discharged the amount of heat of emitting, guaranteeing the radiating rate in the convertible frequency air-conditioner, and lower the temperature by convertible frequency air-conditioner, for fixed frequency air conditioner, because can adjust the frequency of output, and then also can adjust electric current, convertible frequency air-conditioner can be worked in the lower situation of power, also just saved the electric energy that consumes.
At this moment, by the filter suction strainer except in refrigerant gas or the refrigerant liquid because the impurity of air-conditioning duct, preventing the obstruction of air-conditioning duct, and this filter can also be with functions/drying, with the moisture in the filtering cold-producing medium, prevent from air-conditioning duct, occurring the stifled situation of ice.
In order further to promote the efficient of evaporimeter absorbing heat, make the liquid rotating of HTHP in the condenser become the liquid of low-temp low-pressure by choke valve, to finish better the circulation of cold-producing medium in air-conditioning duct.
Further, can also blower fan be set respectively in the position of condenser and evaporimeter, by the blower fan communication base station that rapidly heat shed, or cold air be come in and gone out in the communication base station, improve the cooling efficient of convertible frequency air-conditioner with this.
Temperature is 45 degree in the station, and environment temperature is 37 when spending, and determines in the station that the temperature gap of temperature and environment temperature is 8 to spend; At this moment, temperature gap on the occasion of and less than the temperature difference threshold value that sets, heat in the communication base station that then sheds by heat exchanger is difficult to temperature in the station is maintained target temperature, need to distribute the heat in the communication base station by the combination of convertible frequency air-conditioner and heat exchanger, to reach the purpose that communication base station is lowered the temperature.
When communication base station is carried out combination, start simultaneously convertible frequency air-conditioner and heat exchanger, communication base station is dispelled the heat, wherein by convertible frequency air-conditioner with by heat exchanger respectively with described above identical, repeat no more.
The temperature-controlled process of a kind of communication base station provided by the invention, temperature, outer environment temperature and the temperature gap of interior temperature with respect to environment temperature of standing of communication base station in the station in the communication base station that passes through to obtain, compare with the target temperature that sets and temperature difference threshold value, to determine rational temperature regulation mechanism; When temperature gap is negative value, by applicable scene wider, with respect to the fixed frequency air conditioner mode the less convertible frequency air-conditioner mode of the infringement of electrical equipment is carried out the control of temperature; When temperature gap during greater than temperature difference threshold value, carry out temperature control by the less heat exchanger mode of energy consumption; In the station temperature be on the occasion of and during less than temperature difference threshold value, by lower the temperature efficient preferably the combination of convertible frequency air-conditioner and heat exchanger communication base station is lowered the temperature fast, thereby keep better the interior temperature of communication base station.

300, judge relation between heat-exchange time and the set time threshold;
301, when heat-exchange time during greater than set time threshold, temperature in the measuring station again then.
After by heat exchanger communication base station being lowered the temperature, refrigerant liquid or refrigerant gas flow between heat exchange manifold, take the heat in the communication base station out of communication base station; Behind one section heat-exchange time, for example 1 hour, again the interior temperature of standing is detected by temperature sensor, set heat-exchange time can arrange according to actual conditions, does not limit at this.
302, judge the relation between the temperature and target temperature in the station of again detecting;
303, when temperature is greater than described target temperature in the station of again detecting, then open convertible frequency air-conditioner, by described combination described communication base station is lowered the temperature.
At this moment, if temperature still is higher than target temperature in the station, problems such as may occurring obstruction in the heat exchanger is described then, the cooling-down effect of heat exchanger is descended, can't satisfy the cooling requirement to communication base station; At this moment, start convertible frequency air-conditioner and continue to keep the heat exchanger running, by the combination of convertible frequency air-conditioner and heat exchanger communication base station is lowered the temperature, so that the temperature in the communication base station can remain under the target temperature.Wherein, adopt convertible frequency air-conditioner to lower the temperature with respect to the situation that adopts fixed frequency air conditioner to lower the temperature, it is less to start frequency, and corresponding starting current is also less, and can keep low-frequency work, so also reduced the energy consumption of combination work.
